Stop all Docker containers

I will often run this command to make sure all my docker containers are stopped and removed before running docker-compose up. Sometimes when you restart your system, old containers will start back up automatically in the background.

docker stop $(docker ps -aq) && docker rm $(docker ps -aq)

Storing files on S3 with Elixir

I have this abstraction in my application code called a "CloudFile". This is where I store in the database information about files on S3 and it gives me a resource for other resources to own. For example, a user would have an avatar_cloud_file_id. On the front-end, I would load this relationship and display the avatar with user.avatar_cloud_file.download_url

defmodule RL.CloudFile do
  use Ecto.Schema
  import Ecto.Changeset
